My current mirrors are large, square, and flat on the front. I have been considing the idea of designing a dome on the front and producing it on a 3d printer to add a bulett shape to the front. Since I have a canopy with no windows on the sides, I really do need my mirrors WITH cheaters to check my blind spots so reducing the size of the mirror is not really an option for me.

I like the fish fin idea to produce a raised low presure zone, however, I fear the flow disturbance my futher inturupt atached flow down the side of the car past the mirror. Hard to say without some testing. Maybe someone could provide some detailed data on mirror shapes and CD??
